UNITED STATES PATENT ,OFFICEA i WILLIAM A. MOELLER, F LOS ANGELES, CALIFORNIA, ASSIGNOS?, TO THE LOS ANGELES SPRING BED COMPANY, OF LOS ANGELES, CALIFORNIA FOLDING BED Application filed February 28, 1927. Serial No. 171,502.

This invention has to do with a folding bed and has particular reference to a bed of the type known, generally, as a day bed. It is a general object of my present invention to provide a foldingbed of the type men tioned, which is simple of construction, practical and simple to operate.

Itis a primary object of my present invention to provide a folding bed including two bed frames connected so that one is operated by or from the other so that a person can operate the bed easily and without great exertion.

Another object ofy my present invention is to provide a simple, effective and practical mechanism for-interconnecting the frames of a day bed, or the like.

Another object of my invention is to provide a vbed of the type mentioned having ample space for bedding when the parts are collapsed or folded.

It is another object of my invention to provide abed of the type mentioned which operates freely and easilyl without the aid of spring counterbalances, or the like.

The various objects and features of my invention will be best` and more fully understood from the following detailed description of a typical form and application of the invention, throughout which description reference is had to the accompanying drawings, in which:

Fig. 1 is a sectional view of the bed pro vided by my invention, showing it in folded or collapsed position and showing the inner bed frame indicated in dotted lineskto avoid confusion;

Fig. 2 is a sectional view of the construction, showing the bed open or an extended position;

Fig. 3 is a front elevation of a part of the bed with` the parts in the folded position, being a view taken as indicat-ed by line 3-3 on Fig. 1; and

Fig. 4 is an enlarged, detail, sectional View, taken as indicated by line i--t on Fig..1..,y

The construction provided by my invention includes, generally, a base 10, an inner bed frame 11, an outer bed Vframe 12, a mountingl 13 for thel inner bed frame, a mounting 14 for the outer bed frame,l and means 15 connecting the mountings whereby the frames operate together.

The base 10 is preferably a rectangular structure including a back 16, a front 17 and ends 18. It is to be understood that the base may be constructed of wood, metal, or any other suitable material, and that it may be made of any suitable design or may be ornamented or decorated in any suitable manner. In the drawings, I have shown a base construction inV which the ends 18 include metal plates 18o; which extend between and connect the front and back, and outer parts 185 which connect to the outer sides of the plates. The outer parts 18?) may be decorated or finished in any suitable manner. The base 10 is proportioned to receive Vor hold the innerbed frame 11 so that the frame 11 is movable vertically in the base between a down position, as indicated in dotted lines in Fig. `1, and an up position, as shown in Fig.V 2. Further, the base is designed to receive and support the outer frame 12 when thebed is in the folded position, as shown in Fig. 1. y

The bed frame 11 is preferably a rectangular frame, formed of Aangle iron, or the like, made to suitably fit within the base 10. In practice, I mayprovide vertical guides20 iny the corners of the base v10 to guide the corners Yof the frame 11 as it is moved vertically in the base. ,Y Further, I may provide stops or rests 21 inthe base 10 to receive and support the frame 11 in its down position, as shown in Fig, 1. f

In accordance with my invention, the mountings for the frames and the parts connected therewith are provided at the two ends of the structure. The construction at the two ends of the structure being the saine, I will describe in detail the parts at one end, it being understood that such description applies also to the other end.

The mounting l?, for the bed frame ll, whereby the frame is connected in the base, includes, generally, two hellcranls il and P and a connection between the bellcranks whereby they operate together. In the preferred arrangement, the two bellcranks are mounted on the plate 18a. at the end of the base. The bellcranks have long arms 22 which carry the frame ll, and short arms 23, which are connected together by links 2li and 25. The bellcranks are mounted by means of pivot pins 2G in suitable spaced relation on the plate so that their long arms engage the frame 1l to operate it vertically, In the operation of the bed, the bellcranks move between the positions shown in Fig. l rnd those shown in Fig. 2 and, in thus moving, the outer Vends of the long arms 22 swing` or have an arcuate movement. The frame ll moves straight up and down. Therefore, it is necessary to provide a sliding comiection between the outer ends of the arms 22 and the frame 11. In the drawings, I have shown rollers 26a mounted. on the outer ends of the arms 22 and I have shown suitable brackets 27 on the frame l1, which receive and hold the frame 11 on the rollers allowiim` the rollers to move the necessary amount horizontally relative to the frame. The links 24; and are connected by pivot pins 28 to the outer ends of the short arms 23 and are pivotally connected tog/ether by a pivot pin 29. This link connection between the bellcranks causes them to operate together or in unison when the bed is actuated as will be hereinafter described.

The mounting ldiprovided for the outer frame 12 includes two links 30 and 3l pivotah ly connected to the frame l2 and to the end plate 18a of the hase l0. The foremost link 30 is pivotally connected with the frame 12 by a pin 32 and may be pivotally connected with the plate 18e by the pivot pin 2G which connects the foreinostbellcrank A with the plate 18a. The inner or rear link Si is pivotally connected with the freine l2 by a pin 33 and is pivotally connected by a pin 3st with the plate 18a, at a point intermediate the. two bellcranks. The link 8O is preferably arranged between the hellcrank A and the plate 18a, and is provided with an etitension 30a so that it has an ei'lective hriring on the plate 18o and is. therefore. effective in holding the frame l2 steady during operation of the bed. The links 3() and 3l are proportioned so that the frame 12 can be swung between an in or folded i'iosition. where it is supported on the base. and :in out or extended position where it projects forward from the base and is in a horizontal position in substantial horizontal alignment with the inner frame ll when the inner frame is in its up position. Notches or openings (SO are provided in the base at the point of junction of the front and end parts 18o. These openings pass or receive the links 3() and 3l when the bed is extended, as shown in Fig. 2 of the drawings. In practice, the frame l2 may be a rectangular frame formed of angle iron, or the like, and when forming the frame of angle iron, the angle iron may be faced outwardly so that it has flange parts 35 which overl `ing or rest on the back and end parts 181) of the base when the frame is in the in position, as shown in Fig. l.

Legs 37 may be provided on the forward end of the frame 12 to support the outer end of the frame l2 when the frame is in the extended position, as shown in Fig. The legs are preferably designed and ynfopor tioned to cover the openings in the hase when the bed is folded, as shown in Fig. l.

The connection between the mountings whereby the two frames operate together in the desired manner includes an arm 10, eX- tending or projecting from the end of the link 3l beyond the pivot pin 3l, and a yoke or notch at the end of the link 25 to receive the end of the arm 110. In practice, I pro- `"ide a pin or projection t2 on the outer end of the arm 40 to lit or cooperate with the notch S0 in the end of the link In accordance with my present inif'ention, the arm d() is spaced from or is out of co-opcrative engagement with the link 25 when the outer frame 12 is in the in position, as shown in Fig. l, and does not engage the link 25 until the outer frame 12 has been lifted and swung forward to a position where it is ready to be lowered to its operating position, as shown in Fig. 2. .After the proj ction Ll2 on the arin et() engages the link 25, lowering of the outer frame to its extended position causes operation of the link 25 in a manner to swing the bellcranks between the position shown in F ig. l and that shown in Fig. 2, which operation causes the inner frame to be lifted yfrom the position indicated in Fie'. l to the position shown in Fig. 2. IVith this arrangement, the weight of the outer frame counterbalances the weight of the inner frame, making the bed open very easily. Likewise, when the bed is being closed. the inner frame lowers as the outer frame lifted and. therefore, counter-balances the outer frame.

I may provide stops 6l and 62 to stop the bellcranks A and B in the down position. as shown in Fig. l. Further, I may provide stops (i3 and 64. to receive the linl s2-f-tl and 25 in the down position, :shown in Fig. l. In practice, I provide sonic loose-ness inthe connection between the links-1 2i and 25 to allow for proper operation by the arm l0. Further, I may curve the link 2l, as shown in the drawings, so that it will not interfere with the pin 42 on the end of the arm 40.

It will be obvious that the frames ll and l2 may be equipped with suitable springs 70 and coverings 7l so that the extended structure forms a comfortable bed. With my construction, I can obtain a substantial space between the frames in the folded position to carry bed clothing.

Having described only a typical preferred form of my invention, I do not wish to limit myself to the specific details set forth, but wish to reserve Lto myself any changes or variations that may appear to those skilled in the art or fall within the scope of the following claims:
